Assume that a program requires the execution of 125x106 FP (floating point) instructions, 130x106 INT (integer) instructions, 150x106 L/S (load/store) instructions, and 110x106 branching instructions. These instructions have CPIs of 1, 1, 8 and 4, respectively. Assume that the processor has a 5 GHz clock rate.     a. Is it possible to run the program twice as fast if we improve the CPI of just the L/S instructions? If so, by how much? Show your calculations.     b. What is the Speedup in the execution time of the entire program if the CPI of INT and FP instructions is reduced by 40% and that of L/S and branching instructions is reduced by 50%?
